Continuous Integration Continuous Integration Setup The below diagram illustrates the end to end Continuous Integration (CI) setup which is often used across projects. As seen in the figure, the main actors include the Development team, the Source Control Server and the Continuous Integration server. Developers check-in the code into source control server which is integrated with CI server. For each build, CI server is configured to run functional test cases, code quality checks and provide notifications for any failure scenario which enables the development team to take immediate action. This continuous automation chain helps in reducing the overall defect density and thereby improving the code quality
